Thanks for the query.
I understand your concern.
As blood test for pregnancy gave negative result there is less possibility of pregnancy.
But if conception occurred one to two weeks before blood test, it may not detect the pregnancy.
So, go for urine pregnancy test now.
If test gives negative result, there is less possibility of pregnancy.
In that case, please do consult your doctor, get evaluated and take tablets for withdrawal bleeding.
